SPECIFICATION forming part of Letters Patent No. 404,596, dated June 4, 1889.

Application filed February 25, 1889. Serial No. 301,070- (No model.)

To all whom it may concern.-

Be it known that I, FRANK G. CALDWELL, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of lVest Virginia, have invented a new and useful Improvement in Sheet-Metal Packages, of which the following is a specification.

The object of this invention is to provide a novel sheetmetal package which can be conveniently transported without liability of injury from rough handling or accidental blows.

The object of the invention is accomplished in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a central longitudinal section of a cylindrical package of metel sheets prepared and secured according to my invention. Fig. 2 is an end view of the package. Fig. 3 is a plan of one of the guards for the package ends. Fig. 4 is a plan of a portion of the ut-er metal sheet with side edges turned to engage correspondingly turned or folded edges of the guards. Fig. 5 is a plan and section of a portion of the outer sheet, showing the guards engaged therewith.

The reference-numeral 1 designates the metal sheet or sheets rolled in cylindrical form, as usual, at central space 2 being left to prevent the sheet or sheetsfrom being caused to break or buckle by being bent or curved on too short a radius. This central space may, if desired, be utilized for inclosing caps, anchors, tools, or other small articles that are sometimes put up in such packages.

As shown in Fig. 4, the side edges of the outer portion of the outer sheet are bent, folded, or lapped inward from the outer end of the sheet for a distance equal to the intended circumference of the package, thus forming at each end of the sheet-1netal roll a fold or lap 3, that is adapted to receive and engage a corresponding fold or lap 4 on one edge of a metal guard 5. (Shown in Fig. In Fig. 5 is shown the manner in which the guards 5 are engaged with the side edges of the outer portion of the metal sheet. If clesired, the guards 5 may be slightly longer than the laps or folds of the metal sheet to allow for any slight spring of the sheet metal when rolled in cylindrical form.

After the metal guards 5 have been attached, as shown in Fig. 5, they are rolled with the outer end of the outer metal sheet to complete the sheet-metal roll, which is then secured by nailing said guards to crossed wooden strips 6 and 7, that are inserted into the ends of the roll, as shown in Figs. 1 and 2.

Each wooden strip 6 is provided on its inner side wit-h a central circular projection 8, that may be formed on or secured to said strip in any convenient manner. By means of these circular projections or blocks 8 the package is braced internally at both ends, and thereby kept more readily in a proper cylindrical form.

In the outer side of each wooden strip 6 is a recess 9, that receives the cross-strip 7, so that the outer surfaces of both strips will be flush, and thereby afford a firm support upon which the package may turn or stand.

After the metal sheets have been rolled with guards 5, attached as described, the wooden strips 6 may be placed in position and secured by nails 10, and the strips 7 be then secured in place in like manner; or the strips 6 and '7 may be connected before they are placed in the ends of the sheet-metal roll. If desired, the outer edge'of each guard may be wired or formed with a bead 12, as shown. This manner of constructing sheet-metal packages for storage or transportation is simple and inexpensive, and affords a suitable and efficient protection for the edges of the metal sheets.

That I claim as my invention and desire to secure by Letters Patent, is e 1. As an article of manufacture, a sheet or sheets of metal rolled into cylindrical form and having folds or laps formed on the side edges of the outer portion of the outer sheet and surrounded at each. end with metal guards having lapped or folded edges that engage the folds or laps on the metal sheet, said guards being also secured to wooden cross-pieces at the ends of the roll, substantially as described.

2. As a new article of manufacture, a sheet or sheets of metal rolled into cylindrical form and having folds or lapsformed on the side edges of the outer portion of the outer sheet and surrounded at each end with metal guards having lapped or folded edges that engage the folds or laps 011 the metal sheet, said guards being secured to wooden. cross-pieces both ends, the recessed wooden strips 6, having blocks or projections 8, entering the said roll, and the wooden strips 7, engaging the recesses in the strips 6, said strips being secured to the metal guards, substantially as described.

In testimony whereof I have affixed mysignature in presence of two Witnesses.

FRANK G. CALDWELL.
